Definitions

  • the invention is based on a drive arrangement for a traction device for a mobile seat unit, for example a hospital elevator, comprising a handlebar support with a steering arm and a fork part, a handlebar being arranged on the steering arm and a drive wheel being arranged on the fork part and the steering arm being about a pivot axis is pivotally mounted on the fork part.
  • the traction device can usually be connected to the mobile seating unit to be driven.
  • the towing device has a manual and/or a motor drive.
  • chain drives are used in conjunction with hand cranks. The chain drive drives the drive wheel of the towing device so that the mobile seat unit connected to the towing device can be moved.
  • the JP 2003339782 A discloses an electric drive of a wheelchair with a mounting base plate removably attached to left and right frames on the front of the wheelchair body with a holding mechanism, and a steering part having a steering shaft penetrating the mounting base plate, the steering shaft being pivotable about a horizontal pivot axis.
  • the DE 90 11 220 U1 discloses a hospital elevator with a drive unit that is designed to be foldable.
  • a handlebar tube is divided into two and has a folding joint which is arranged above an upper end of a control tube.
  • a drive arrangement for a traction device for a wheelchair is known.
  • the drive arrangement described there has a handlebar support with a steering arm and a fork part with a drive wheel.
  • the handlebar is designed as a hand crank.
  • the drive wheel can be driven via a drive chain in conjunction with a torque transmission unit and an output chain.
  • electric motor support There is also the option of electric motor support.
  • While such a towing device can enable a user to move with little effort with a mobile seat unit, transporting the towing device in conjunction with the mobile seat unit has so far been difficult. For example, when transporting in a car, the towing device must be loaded into the car in addition to the mobile seat unit, which results in an increased need for storage space in the car.
  • the object of the present invention is therefore to offer an improved drive arrangement for a towing device as well as an easily transportable, yet flexibly adaptable towing device for a mobile seat unit.
  • a drive arrangement for a towing device for a mobile seat unit comprising a handlebar support with a steering arm and a fork part, a handlebar being arranged on the steering arm and a drive wheel being arranged on the fork part and the steering arm being pivotally mounted on the fork part about a pivot axis
  • the handlebar support, in particular the steering arm is designed and / or arranged asymmetrically to the center plane of the drive wheel in such a way that the steering arm can be pivoted completely or at least partially on a pivoting side of the drive wheel up to next to the drive wheel when pivoting about the pivot axis, whereby the Pivoting side represents the side of the drive wheel along which the steering arm can be pivoted completely or at least partially to next to the drive wheel.
  • a basic idea of the invention is therefore to design the drive arrangement in such a way that the steering arm can be pivoted as far as possible, in particular up to next to the drive wheel.
  • a towing device equipped with such a drive arrangement can be folded or packed down to a particularly small pack size.
  • the steering arm can be pivoted completely on the pivoting side of the drive wheel up to next to the drive wheel.
  • the steering arm only at least partially, for example at least a quarter, preferably at least half, until it can be pivoted next to the drive wheel.
  • the handlebar support can be designed asymmetrically in such a way that the steering arm can be pivoted through a particularly large angle without parts of the steering arm colliding against other parts of the towing device, in particular against the drive wheel, when pivoting.
  • the steering arm can be pivotable forward, i.e. in the direction of the usual direction of travel, and/or backwards, i.e. against the usual direction of travel.
  • the pivot axis can run perpendicular to the center plane of the drive wheel.
  • the swivel side represents the side of the drive wheel, i.e. the left or right side of the drive wheel in accordance with the usual direction of travel, along which the steering arm can be swiveled completely or at least partially up to next to the drive wheel.
  • “Next to the drive wheel” can be understood to mean the area of the respective half-space defined by the center plane of the drive wheel and associated with the pivoting side, which extends from the ground to the top edge of the drive wheel when the drive wheel is in the upright position that is usual for driving the tractor.
  • the pivoting side can be defined by the position of the center of gravity of the handlebar support or the steering arm relative to the center plane of the drive wheel.
  • the pivot side can be defined in that the center of gravity is located in the left or right half-space defined by the center plane.
  • the steering arm can have at least two steering arm rods.
  • the stiffness of the steering arm and thus its stability can be improved while keeping the weight low.
  • the at least two steering arm rods are arranged and/or can be arranged in the half space associated with the pivoting side.
  • the steering arm rods can be arranged and/or can be arranged in the same half-space defined by the center plane of the drive wheel.
  • the handlebar can then be arranged and/or guided on two steering arm rods, in particular by means of a handlebar holder located between the two steering arm rods.
  • the steering arm can be arranged and/or supported on the fork part via an additional support on the side of the handlebar support opposite the pivoting side.
  • the additional support can have a smaller width than the steering arm.
  • the point of application of the additional support on the steering arm can be selected such that the largest possible maximum pivot angle is maintained.
  • the additional support can engage only one of the steering arm rods.
  • the drive arrangement can have a manual drive.
  • a crank drive in particular a hand crank
  • the crank drive can be connected to the drive wheel in a torque-transmitting manner via a drive means, in particular a drive chain, a torque transmission unit and an output means, in particular an output chain.
  • the drive means and/or the output means can each preferably be designed as a chain. Alternatively or additionally, however, it is also conceivable to design the drive means and/or the output means as a belt, rope and/or as a spindle.
  • the Drive wheel can thus be driven by actuating the crank drive, with a torque generated on the crank drive being transferable to the drive wheel via the drive means, the torque transmission unit and the output means.
  • a gear ratio or the like can be provided along this path in order to appropriately convert the torque generated at the crank.
  • the torque transmission unit can be designed as a gear.
  • the towing device can be folded particularly safely if the drive means are guided in the steering arm and/or the output means are guided in the fork part. Thus, for example, when pivoting the steering arm, the drive means can be safely "stowed away". If the drive means is designed as a drive chain, the drive chain can, for example, fall off from a crank drive gear located on the handlebar during pivoting of the steering arm. Injuries to the user due to contact with the drive means or with the output means while traveling with the towing device can also be avoided.
  • a further space saving can be achieved if the drive means and the output means are arranged in the same half-space defined by the center plane of the drive wheel, in particular in the half-space belonging to the pivoting side.
  • the drive means and the output means can therefore be guided relatively close to one another.
  • additional space can be created within the drive arrangement for arranging further elements of the drive arrangement, for example for arranging the torque transmission unit.
  • the torque transmission unit can have at least one shaft that is arranged coaxially to the pivot axis.
  • the torque transmission unit can have at least two have coaxially arranged shafts, in particular a drive shaft assigned to the drive means and an output shaft assigned to the output means.
  • the two shafts can each be arranged coaxially to the pivot axis.
  • the drive arrangement comprises at least one, in particular electric, motor, wherein the at least one motor can particularly preferably be designed as a hub motor and/or as a mid-mounted motor.
  • the motor can be designed to support a manual drive.
  • the motor can also be designed to independently drive the towing device or a mobile seat unit connected to the towing device.
  • a power selector lever for example electrically connected to the engine, can be provided on the handlebar to control the engine.
  • the power delivered by the motor can be controllable depending on a manual power applied by the user and/or a torque applied by the user.
  • the motor can be controllable and/or controlled in the manner of a pedelec.
  • a motor designed as a hub motor can be arranged in particular on the hub of the drive wheel.
  • Such a hub motor usually offers the advantage of particularly quiet operation.
  • a motor designed as a mid-engine can be operated at speeds (largely) independent of the speed of the drive wheel, in particular by means of a suitable transmission gear. This makes it possible to achieve particularly efficient operation of the mid-engine. Furthermore, heat problems, for example when driving uphill, can be avoided or reduced more easily than with a hub motor.
  • the drive arrangement can be produced particularly flexibly and cost-effectively if a commercially available motor is used as the motor.
  • a motor that is commercially available for Pedelecs.
  • Such Pedelec motors are usually tailored to the torques or forces that occur when a user of a Pedelec or the like drives their legs.
  • the transmission ratio between the crank drive and the drive shaft and/or a motor shaft is set such that the speed of the drive shaft and/or the Motor shaft is at most as high as the speed of the crank drive.
  • the motor can preferably be designed as a mid-mounted motor, because in this case a motor of a pedelec that is otherwise designed or usable as a bottom bracket motor can also be used for the drive arrangement.
  • the motor which is designed as a mid-engine, can be positioned largely freely on the drive arrangement, in particular on the handlebar support.
  • the motor can preferably be arranged adjacent to the torque transmission unit.
  • a drive axle of the motor can be arranged parallel to the pivot axis, in particular offset upwards according to the position of use of the towing device.
  • this can also be used by the engine.
  • the motor can act either on the drive means, on the torque transmission unit or on the output means.
  • the arrangement of the motor adjacent to the torque transmission unit facilitates pivoting of the steering arm.
  • a tank or battery or the like required for operating the motor can be arranged in and/or on the handlebar support, in particular in and/or on the fork part, so that this also enables the steering arm to be pivoted as widely as possible and thus a further reduced pack size.
  • an installation space adjacent to the pivot axis and/or around the pivot axis is designed to accommodate the torque transmission unit and/or the at least one motor.
  • the installation space can be used in particular for modular, optionally equipped with a torque transmission unit and / or with at least one motor. This makes it possible to design a modular, modular system of towing devices or drive arrangements for towing devices.
  • the installation space can be adapted, in particular dimensioned, to different types of torque transmission units and/or different types of motors. Then, depending on the requirements, a suitable torque transmission unit or a suitable motor can be used. Especially in the case of low performance requirements, smaller motors can be used, which also reduces the pack size.
  • the packing size that can be achieved for transport purposes can be improved if the handlebar is designed and/or arranged to be displaceable on the steering arm and/or pivotable relative thereto. This also increases the ease of use for the user.
  • the handlebar or the crank drive arranged and/or designed on the handlebar can also be used by moving and/or pivoting as a replacement for an otherwise required chain tensioner, in particular in the case of a drive means designed as a drive chain.
  • At least one parking support in particular one that can be folded in and out laterally, is arranged and/or formed on the handlebar support, in particular on the fork part, then the towing device can be parked independently of the mobile seat unit.
  • the parking support can be folded to the side to ensure a small pack size.
  • the drive arrangement in particular the handlebar support, has at least one latching device.
  • the latching device can be set up to releasably fix the steering arm in at least one pivoting position.
  • a locking position for an end pivot position for use when driving, i.e. H. with the steering arm folded out.
  • a further locking position can be provided for an end pivot position for transport, in particular when the tractor is folded to the maximum.
  • a locking position for a central pivoting position for convenient connection of the towing device to the mobile seat unit is also conceivable.
  • the scope of the invention also includes a towing device for a mobile seat unit, which comprises a drive arrangement according to the invention.
  • the mobile seat unit can be a hospital elevator or a wheelchair, a recumbent bicycle or the like.
  • the mobile seat unit can also include vehicles for transporting people, which can usually be driven at least manually, such as strollers or the like.
